6,8,10 made for my little girl's bithday party. I made a pretty fondant number 5 for the topper but naturally, it broke in half just as I was putting it on the cake. I had some extra peonys that i had already made so I used those instead. I had planned to use the large flowers on the middle and bottom tiers but I didn't have enough room to perch them. I really need to plan these things out in advance before going all willy nilly on the day of. Buttercream with fondant decorations and flowers. the 6 and the 10 are 4" tall and the middle tier is only 3". She loved the cake and that's what mattered most.
